Moeller HPL0211-2007/2008
Selectivity 415 V AC
between circuit-breakers enables separate shut-down of faulty system sections.
Selectivity (discrimination) exists between incoming breaker 1 and outgoing breaker 2 if,
only outgoing breaker 2 trips at position 2 during a short-circuit.
System sections 3 and 4 continue to be operational.
